HUBERT KRANTZ, OF BROOKLYN, NEW YORK.

OUTLET-BOX.

SPECIFICATION forming part of Letters Patent No. 749,442, dated anuary12, 1904.

Application filed May 25, 1903. Serial No. 158,703. (No model.)

To all whom it may concern.-

Be it known that I, HUBERT KRANTZ, a citizen of the United StatesofAmerioa, and a resident of theborough of Brooklyn, in the county ofKings, State of New York, have invented an Outlet-Box, of which thefollowing is a specification.

In the accompanying drawings, Figure 1 1s :1 a sectional view of a boxembodying my invention. Fig. 2 is an enlarged inner face view Fig. 4 isan outer view of a modification.

In the drawlngs I have shown my invention as applied to asheet-steelconstruction of box;

but I do not limit myself thereto.

, A is the box, in the side walls of which are punched or otherwiseformed circular openings a of a size suitable for the admission of Thepieces of metal metal B of the same size may be used to plug up theholes again, although the disks and the openings are of the samediameter throughout,

I form ears I) at the which will be the outer face when the disk isThese ears are expanded out of the periphery, Figs. 2 and 3. At the leftof Fig.

l I have shown a disk B so fitted into its 1 openingin the side wall ofthe box and wedged in place there. The disk can be knocked outward tofree the opening for the introduction of a conduit-pipe when desired;but owing to the projecting ears 6 the disk cannot be forced into thebox to interfere with the wires or to permit the admission of mortar,plaster, or other harmful material.

Instead of forming the projecting ears on the disks they may be formedon the box on the inner face of the walls at the openings, as indicatedat b, Fig. 5. In this case the ears project radially inward.

I claim as my invention 1. The herein-described electrical outletbox,having openings with removable disks punched out of the metal of thebox, and fitting within said openings, and radially-pro j ecting earsexpanded out of one of said parts to prevent said disks from beingforced inwardly into the box, substantially as described. 2. Theherein-described electrical outletbox, having openings with removabledisks fitting within said openings, said disks havingradially-projecting ears expanded out of the metal of their peripheries.and adjacent to their outer faces only, to prevent the disks from beingforced inwardly into the box, substantially as described.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.

HUBERT KRANTZ.
